IMPROVEMENT IN ELEVATORS FOR LOADING CARS.

I Specification forming part of Letters Patent No. 4l ,482, datedFebruary 9, 1864.

. .To all whom t may concern.-

Be it known that I, RICHARD D. GHA'rTER- TON, of Bath, in the county ofSomerset, in that part of the United Kingdom of Great Britain andIreland called England, now temporarily residing in Cobourg, in theProvince of Canada, have invented a new and improved elevator forloading locomotive tenderswand carsv and other carriages with wood,coal, and other freight; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe accompanying drawings, making a part of this specication, in which-Figure 1 is a front elevation of my invention; Fig. 2, a side sectionalview of the same taken in the line x x, Fig. 1; Fig. 3, a horizontalsection of thesame taken in the line y y, Fig. 2.

Similar letters of reference indicate corresponding parts in the severalfigures.

Thisinvention relates to a new and useful device for loadingfreight-conveying vehicles, whereby a great saving in labor and time iseffected. The invention is more especially designed for loadinglocomotive-tenders with wood or coal and cars with freight, but it maybe advantageously used in many cases for loading other vehicles orcarriages.

The invention consists in the employment or use Yof a risingand-fallingtray operated through the medium-of pulleys and ropes, the latter beingattached to a wheel or pulley provided with grooves so arranged th atwhen the platform reaches the necessary or desired height it will beautomatically tilted to discharge its load.

The invention also consists in the employment or use of a division-boardarranged with the tray in such a manner that it may be convenientlyadiusted for dividing the tray into two equal compartments when only halfof a tray-load is required to, be dumped or tilted into a car orcarriage, and also be capable of being removed out of the tray when notrequired for use.

The invention further consists in a self-adjusting fastening to securethe swinging side of the tray in a closed state while the latter isbeing elevated and admit of said side swinging open when the tray istilted to discharge its load.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A represents a framing, composed of two uprights, a a, connected attheir upper ends by a cross-piece, b, and attached at their lower endsto a base plate, c. L

B is a platform, composed of two distinct or separate longitudinalparts, l 2, each part being comprised of a horizontal board, d, havingan upright board, e, at each end. The boards e at each end of the boardsd are fitted between guides j' at the inner side of the uprights a a, toinsure a vertical rising-and-falling movement of the two parts of the,platform B. The rear part, 2, of the platform has friction-rollers g atits front edge, as shown in Fig. 2. These two parts l 2 of the platformB 'are elevated by separate ropes C C', which pass under and overseparate pulleys h h in the uprights a ce', but are attached to one andthe same hoisting-pulley, D, which is placed horizontally underneath thebase-plate I c. This hoisting-pulley D is provided with three grooves,Ai i fi", made circumferentially in its periphery. The central groove,t, receives a rope, E, by which the pulley D is turned, and the groove ireceives the ropes C, which are connected with the rear part, 2, of theplatform B, while the groove i" receives the ropes C', which areconnected with the front part, 1, of the platform. The groove i is not aperfect one-that is to say, it does not extend all around the pulley Dat the same depth, but has two deep cuts or recesses, jj, which are madehorizontally into the pulley at opposite sides of its axis 7c, as shownclearly in Fig. 3.

On the platform B there is placed a rectangular tray, F, which isconnected by pivots l to the front part, 1, of the platform B, the backpart of the tray F simply resting on the rear part, 2, of the platform.The pivots Z are near the front and bottom of the part 1 of theplatform, as shown clearly in Fig. 2.

At the front side of the tray F there is suspended a door, G, the pivotsm of which are at the upper part of the tray. This door or slide G iskept in a closed state when not intended to be open by a catch, H',which is simply a bent rod having its back end fitted loosely on a pin,n, at the under side of the part 2 of the platform, the front part ofsaid cord, r, attached to its upper edge, one nearl each end, and saidcords pass over pulleys s s at the top of the framing A, and haveweights t attached to them. e

From the above description it will be seen Ithat when the pulley D isturned in the direction indicated bythe arrow the platform AB willbeelevated, the two parts 1- 2 of the-platform moving upward with the samespeed and in the same horizontal plane until the ropes Greach the endsof the perfect portion of the groove and enter the c uts j j,

which causefthe speed of the ropes C/ to be less than that of the ropesC, and con- ,.sequently the rear part, 2, of the platform B will ascendquicker than the rfront part, 1, and when the part 2 reaches a certainelevation above the part l the tray F will be tilted and the door orside G of the tray will be relieved from the catch H, so that the dooror side may swing` open and the contents of the tray discharged, asshown in red in Fig. 2.

When the rope E, by which the-pulley D is turned, is released from thepower that operated it, the platform and tray descend, and, as well asthe side or door G, assume their original position.

lThe board or partition H, when adjusted in the tray F, admits ofone-halt' a load being discharged from the tray. If, for insta-nce, thetray will hold a cord of wood, onevhalf a cord maybe elevated and dumpedor tilted into the car or tender..

When the invention is used for loading cars, it is designed to `have therope E operated by the train or locomotive, the framing A being placedby the side of the track, as shown in Fig.' 2, the cars being below theplatform and tray when the latter are in an elevated state.

lt will be understood that the ropes C G C OIare attached to the pulleyD at opposite points, as shown in Fig. 3.

Having thus described my invention, what I claim as new, and desire tosecure by Letters l. The rising-and-falling platform B, formed of twoseparate parts, l 2, in connection with the pulley D, provided with agroove, if', having cuts or recesses j j made in it, the platform beingconnected to the pulley D by ropes C C C lC', and all arranged tooperate either with or without the tray F in the manner substantially asand for the purpose herein set forth.

' 2. The division or partition board H, suspended and counterpoisedsubstantially as shown, when used in connection with the tray F, for thepurpose specied 3. The swinging door or side G, in combination with thecatch H', arranged to operate in connection with the platform B,substantially as and for the purpose set forth.
